What is the goal?
The main goal is to reduce pain by eliminating motion at the arthritic joint while correcting ankle alignment when necessary.

Advanced arthritis • stability • pain
Ankle fusion
Ankle fusion joins the tibia and talus to eliminate painful joint motion. It remains a reliable option for advanced arthritis when preserving ankle motion is not the priority or when replacement is not suitable.
Key point
The choice of procedure depends on the diagnosis, alignment, tissue quality, activity level and the patient’s goals. Recovery protocols are individualised.

Visualising the procedure
This illustration shows the principle of ankle fusion: stabilising the joint in a functional position to relieve pain from advanced arthritis.
Goal
Indications
When can it be considered?
- Advanced arthritis with significant pain despite appropriate non-operative treatment.
- Deformity or local factors that make replacement less suitable.
- Priority given to a stable and durable solution rather than preserving motion.
Technique
How is the procedure performed?
Residual cartilage is removed, alignment is corrected, and the tibia and talus are fixed in a functional position using screws and/or plates. Depending on the anatomy and clinical situation, the approach may be open or arthroscopic.
Recovery
What can you expect after surgery?
0–2 weeksProtect
Elevation, pain control and protection of the operated ankle.
6–12 weeksFuse
Weight-bearing is gradually resumed according to X-rays and fusion progress.
Several monthsReturn
Walking and activities are increased gradually; swelling may persist for several months.
Risks & limitations
What are the main trade-offs?
Risks include nonunion, infection, wound-healing problems, hardware irritation and stiffness. The ankle loses tibiotalar motion and neighbouring joints may be placed under greater stress over time.
